Choose Clerk if:
Product teams who would rather ship features than build authentication.
Choose Jenkins if:
Teams with infrastructure skills who need full control or cannot send code to a hosted service.
Clerk: pros & cons
- Prebuilt UI components that look decent by default
- Handles sessions, MFA and organisations
- Strong React and Next.js support
- Pricing per monthly active user adds up
- Deep customisation fights the defaults
- Auth becomes a vendor dependency
Jenkins: pros & cons
- Free and open source with no usage limits
- Enormous plugin ecosystem
- Runs entirely on your own infrastructure
- You maintain the server, the agents and the plugins
- Interface and defaults feel dated
- Plugin quality varies and updates can break builds
Our verdict on Clerk
A big time-saver early on. Understand the per-user pricing curve before your user count grows.
Our verdict on Jenkins
Still the right answer when control matters more than convenience. For most small teams a hosted CI is less work.
